1 To all whom, it may concern: 7

Be it known that I, NOAH 1V. RASNIOK, a citizen of the United States, residing at Nora, in the county of Dickenson and State of Virginia, have invented a new and useful Gate Locking and Operating Mechanism, of

which the following is 'a specification.

The present invention relates to. an improvementin gate locking, and operating mechanism, adapted particularly .for light gates-to be opened and closedbypersons, when entering and leaving an 1nclosure; for

instance,a yard, a mine, behind a counter, an

' oflice rail, and the like.

It is an object of this invention to pros vide a gate of this character with an operating mechanism,which also locks the gate" when closedfan d which may be actuated by a foot pedal to release the lock, andto then open thegate, the invention providing novel 'means for automatically closing the gate when the mechanism isreleased by the person after passing through the gate, the closing means being releasable to permit the gate to remainopen when desired. 7

Another feature of the invention "is to provide a gate locking and operating mechanism of this character, which occupies but relatively small space, which .has'the greater part of the mechanism located beneath the 1 gatc'and out of the way, and which may be applied to gates without detracting from the general appearance and strength ofthe'gate] V The above, and other objects and ad. vantages of this invention, will be more specifically brought out in the following de-v V scription of the present preferred embodi- V ments of the invention, the same being illus:

. fied form of thesupporting arm' used at the Fig. 10 is a detail perspective view of the inner end of one of the operating levers, showing the finger thereon, and showing a portion of the pedal carried bythe finger. a Referring to this drawing, 10 andll des- V ignate a pair of vertical opposed gate sections, which may be of any approved form, and whicl are shown in the present instance as comprising rows of vertically disposed slats, secured in position by upper and lower pairs of V battens 12. and 13, respectively.

Each gate. section is hingedly or pivotally connected tothe upper'ends of supporting arms 14 and 15, the. arms 14 being connected to the inner adjacent endsof the gate sections 10'and"11,1while the arms 15 are connected to the remote" or outer ends of the The arms 14 each. comprise a pair of rods secured at their upper ends, by a pivot bolt 16, against the opposite sides of the adjacent ate section, as shown in'Fig. 8. The rods diverge downwardly from thepivot bolt 16 atthe opposite sides of the adjacent gate 7 section, and have their lower ends turned inwardly at an abrupt angle toward each other to provide, horizontal transversely registering journals 17. These journals 17 are unounted in bearing blocks 18' held, by bolts 19, to the upper face of a base or foundation 20. The bolts 19, as shown in Fig. 3, have their lower headed ends embedded in the preferably cementitious base 20.

The inner ends of the journals 17 of each 7 arm 1a, are bent atsubstantially right angles, and in parallelism with one another,

outwardly away fromthe meetingends of the gate sections 10and11, and are coni nected at their outerendsby a pin or bear- The outer arm 15 ofeach gate section is,

of similar form, with the exception that, as shown in Fig. 4, the inner ends of the journals 17 terminate in spaced apart relation and have no crank portion.

' The bearing blocks 18, which are preferably arranged in pairs, one pair for each journal "17, are spaced apart longitudmally on-top of the base 20, a distance equal to the distance between the pivot bolts 16, which connect the upper ends of the arms 14 and 15 to the upper portions of the gate sections. Such pivoting of the arms 14 and '15 provides, wit-h the gate sections, a parallel motion, by means of which the gate sections rise and fall in their movements toward and away from each other. By this arrangement also, the weight of the gate sections 10 and 11 tend to hold them in their open and closed positions.

Preferably, each gate section is provided with a coiled spring 22, having an arm 23 secured to the adjacent gate section, preferably below the upper batten 12. The opposite arm 24 of the spring is preferably curved downwardly and bent outwardly'at its free end to provide a lip 25 for detachable engagement against the lower end of the arm 15'. This spring 22 is adapted to exert tension upon its adjacent gate section to raise the same and swing it into closed position.

The base 20 is provided with a central longitudinal slot 26, which opens upwardly beneath the gate, and which is in the plane of the gate. The outer ends of the slot 26 are covered by plates 27 suitably secured to the base 20, and which extend ashort distance inwardly toward the meeting ends of the gate sections. A pair of combined look ing and operating levers 28 are placed in the slot 26. The outer end of each lever'28 lies beneath the adjacent plate 27, to anchor the outer end ofthe lever in the slot" 26. The levers extend inwardly toward each other beneath the gate, and, at intermediate points in their lengths, have pivotal connection with the crank portions 21 of the inner supporting arms 14 of the gate sections. The levers 28 are recessed in their upper edges, and at their inner ends, to'provide locking shoulders 29 adapted, when the levers 28 are raised, as shownin Figs. 1 and 2, to engage against depending stops or projections 30 provided on the. gate sections to retain said sections from opening. It will be noted from' the drawings, that there cesses and the shoulders 29 are of such depth that the gate sections cannot be spread apart to move the levers 28. down, and that the levers 28 must, first beforced downwardly at their innerends torelease the shoulders 29 'wardly into a recess 32 formed in'the gate,

by notches cut out of the lower inner corners of the sections 10"and 11. These fin gers 31 are adapted to overlap, and eachhas its free end bearing against the upper edge of the extension 32 of the opposite lever '28, so that both of the levers willbe'depressed' upon the downward movement of-either one of the same. 7

The intermediate or highest portion of each finger 31 is preferably provided with a laterally extending pedal or projection 33, as shown to advantage in Figs. 6 and 10. These pedals 33 are held at a' suitable distance above the upper face of the base 20, by means of the upwardly arched fingers, to provide sufiicient' clearance beneath the pedals to admit of the depression of the fingers and the consequent swinging of the operating levers 28.

The above structure is susceptible of various changes or modifications within the scope of the claims, and one modification is shown in Figs. 8 and 9, of the drawing.

In Fig. 8, the combined supporting and crank arm 14 is disclosed as in the form of a rod, which has its opposite ends secured to a vertical strip 34 adapted to lie fiat against the side of the gate section, the strip 34 swinging with the arm and as a part of the same. The lower end of the strip 34 is pro- I vided with an edgewise projection 21 providing, with the opposed strip 34, a crank portion for the arm 14 In Fig. 9, a modification of the outer arm for supporting one of the gate sections is shown, and wherein the rod 15 issimilar to the rod 15, but is secured at its upper and lower ends to a strip 35, which reinforces the arm 15 and swings therewith, and as a part of the same. In Figs. 8 and 9 only one half of the arms 14 and 15 is shown, and it is understood that the other half is of similar form, and is adapted for'securement against the opposite side of the adjacent gate section.

In operation, when a person approaches the gate and desires to pass therethrough,

cording to the location 'of the gate. 7 The downward movement of the pedal 33 forces the adjacent finger 31 therewith to depress the inner end of the adjacent lever 28. The

free end of the finger engages the ledge orw extension 32 of the opposite operating lever 7 28, and both levers are thus simultaneously I depressed. The outer ends of the levers 28 engage against the anchoring plates 27, and

the downward'movement of the levers, there- 7 fore, draws the cranks 21 downwardly into 'the chambers. or' enlargements 36 of the slot 26.

The downward movement of the cranks 21 turns the adjacent journals 17 and swings the arms 14 outwardly from ea'chiother to separate the gate sections l andcll. The initial downward movement 7 of the inner ends of the operating levers 28, releases the looking shoulders 29 from the gate sections,

as above described, so that the sections may be free, to be raised and swung outwardly the stops 30 of the gate. Thus, the gate is automatically closed and locked when the pedal is released. 7 V V g V Theopening and closing of the gate sections'lO and "11 maybe limited by pins 37 rising from the base 20in the path offstuds- 38 which project laterally from the gate sections, and which strike and rest against the pins 37. The pins 37 are so positioned that the pivotbolts 16 pass outwardly and inwardly over the lower pivotal mounting of the supporting armsla and 15;

The li'ps25 of the springs 22ma-y be leased from the adjacent arms 15, so thatthei gate sections 10 and 11 may rest in'openposi tion against the pins'37.' V 7 7 It is, of course, understoodthatvarious other means than theQpedalsBS be resorted to for the purpose of forcing the combined locking and operatinglevers28 downwardly at their inner ends;
